To all y11s/mnt 'it may com-I1. fi

.ii.\.\'. a ultim-not the lr'nited States, and resident ol" St. Louis,Missouri, have 'invent-ed certain new and n; Corner-Heads, of which thefolloivingis a specification containing a. full, clear. and exactdescription, reference being'had to the accompanying` drawings, forminga part hereof. j

My invention relates to impiovements in corner beads.

.The object oiA my inveiition is to construct a bead proper in the formof an opense-.inied tulle and to provide .in connection with the beadproper a pair of .stifening and supportingr wings each having anintegral. enlarged head which is embraced by .the head proper so as tobe hingedly conneoted with the bead. The wings are constructed of pliantmaterial, which quality, in connection with thehinge referred to,

pern'iitsof an adjustment of the wings relatiif-'e to the bead so thatthe headA may he applied in a. straight. pliinib line upon an unevensurface.

W ith the above purposes in view my invention consists in certain novelfeatures of construction and arrangement of parts as will he hereinaftermore full)v described, pointed out in the claiins and illustrated by theaecoinpanyiiig),r drawings. in whieh Figure 1 is a perspective view of asection of a device en'ibodying i-ny invent-ion; Fig. Q-

' illustrates in sectionall plan my iinproyed corner head as in use;Fig. il is a jwrspective view .of a detachable. cxtenioii lirarket;:in-:l Fig. '-L illustrates in side elevation the. extension bracketas:in use. v

Referring' 'to theaoconipaiiying drawings, in which tin` saine part-sare designated by the saine reference characters in the several views:the bead proper l is a tubular strip of metal, the preferred forni ofwliii'h is plaiioazonrox in cross section, c., halt round, and has inits plane side an open Seam 2.

The supportingT wines 3 for the Aoe-ad l are constructed oi' pliantsheet iiietah and each winer has at one ol its loiigitiidiiuii edges aoil ff wliirli is substantially circular in cross section. The bodyportions ol ear-h of the vines are perforated at intervals, thepcrtoraioiis :3 pciinittin;I` the plaster to lie c eu'ibedded to thcrear of and between 'the wings. At i1;` tcrvals throughout the length:fnl Improvements in 'of each ofthe wings there are holes 6 '-lie itknown-that l, Tiionas H. xINsthrough which nailsy or the like may beili'iren for the securing: of the wings to the' wall. v

In assembling the parts for use the bead l is slipped lengthwise overthe (foils 4 of the two supjmrtingA wings, the body portions ol thewings projeetii'ig,r through the open seam 2 of the bead 1. As clearlyshow n the coils .4. in addition to forming a hinge connection with thebead, serve to reinforce the. bead itself against being indented. Thusthe head .is well as the supporting wings may be constructed ol"comparatively light or thin material. -Xn extension bracket i' hasadjacent to one. ot' its ends and extended froiii une of the. sidemargins;l an ontstanding, integral ear 8; and extended from .Y

the end iiiargin-and adjacent tothe oppo-V site side margin is anear 9which extends at right angles to the first mentioned ear. W itliin thebody of the bracket there is an ear 10 which is stamped out of the bodyof..

the bracket and bent to a position at right angles to the body. j A

In applying the bracketjrefer'ence being.

vhad to Fig. 4 of the drawing, the ear 8 1s .'Lv reason of (he halfround shape of the i bea-.l l. as clearly shoivnin Fig. 2, the beaditself forms a rather large siioiilcle against whirh the. end of theplaster may anchor behind the bead. the'slioulder of the plaster havinga minimum of feather edge., which is advantageous in Plastering in thatvit practically eliminates the cracking olf of. the plaster at thefeather edge.l

A decided and distinctadi-'antage of the construction ot .my bead isthat `the wings arf.l iniilepeutentllv hinged to the bead, therefore. awider range of adjustment may be had. The coils J. ol the wings reinforri the entire length ot the bead itself and tien and i i llr hold thebead, andv'th1-ireby they item1 1:. liability of blows on the headwartung the adjacent plaster.

l. ln device of the class described. a

leo

tubular bead having an open seam Aextending the length of the bead,`apair of pliant sheet metal wings, each winghaving at one.

fof its side marginsan integral coil'extend- 'ing throughout the iengthof the Wing and Y "which' coils fit AWithin the bead and substanltiallyfili the space tnereim and said Wings 'extending outwardiy through theseam, 'whereby said wings are hingedly connected with the bead and thebead; is reinforced throughout its length by said coils.

2. An adjustable metal corner bead comprising a tubular bead portionhaving a Yrounded front side and an open slit extending lengthwise ofits back side, a pair of complementary sheet metal 'strips each having arounded beaded edge, Said strips being varranged in said slit with theirbeaded edges within said tubular bead portionand their opposite edgesdiverging outward, the bead.

ed edges of said stripsbeing in all` angular positions of said wings inContact with each other and withthe front and back sides of said tubularbead portion, whereby Asaid strips are hingedly connected to saidtubular 'bead portion and serve to stiffen the latter.

3. In a device of the c1asS-described,the

combinationvitha tubular bead and a supporting`wing for the bead, whichwing s perforated; at `intervals, of an xtensionf bracket constructed ofsheet metal and prof tially :1s shown and for the purposes stated..

In testimony whereof, I have signed my i name to this specification, inpresence of two l subscribing Witnesses.'
